oEmbed – Easily get the information you need to embed content from viddler, flickr, hooloo, etc… in your pages.
oEmbed is an open standard that allows you to pass a url to an oEmbed provider and get back information about that resource.
i.e. Pass a hulu url to hulu’s oEmbed service: http://www.hulu.com/api/oembed.xml?url=http%3A//www.hulu.com/watch/20807/late-night-with-conan-obrien-wed-may-21-2008 and you’ll get back a json object with details of the video (thumbnail size and url, etc..) and on some oembed services the html needed to embed the video.
